accordance with NFPA 70 E, Part IIand ANSI 2244.1. (

Where it is not feasible to de-energize the unit, the following precautions should be taken:

Persons working near exposed parts thatare or may be energized should be instructed toand should use practices (including appropriate apparel, equipment and tools) inaccordance with NFPA 70 E, Part II.

A.

Persons working on exposed parts that are or may be energized should, in addition to A,be qualified persons who have been trained to work on energized equipment.B.

RECOMMENDED PROCEDURE

The successful and safe operation of medium voltage control equipment is dependent upon handling,installation, operationand maintenance by qualified personnel.Failure to follow fundamental installation andmaintenance recommendations could lead to personal injury and damage to the equipment and otherproperty.

S .•*. * •: *vv1- •* '

RECEIVING

Upon receipt of the equipment, make an immediate inspection for any damages which may have occurredduring shipment When the contactor is received it should be unpacked sufficiently to inspect for concealeddamage and to determine that the shipment is complete and correct if any damage is found it should benoted prior to accepting the shipment if possible.Check for things such as. damage to the container, water seepage or moisture on the contactor. Check thenameplate to confirm that the ratings meet the intended application.

. If any parts are damaged or missing, fife a claim immediately with the carrier and notify the Toshiba salesoffice. Try to give as much information as possible when filing a claim.

HANDLING & STORAGE

Vacuum contactors should be handled with care to avoid damage. Contactors should be kept In an upright

position and moved with suitable equipment.

If the contactor is to be stored over any length of time, the packing material should be restored for

protection during that period. Where conditions permit, the packing should be left intact until the contactor

is ready for installation. Store the contactor in a dry and dust free area. It should not be left outdoors or in

adverse conditions. If unprotected, corrosion, rust and insulation deterioration will occur.

APPLICATION PRECAUTIONS

Verify that the voltage and current applied is within the specified ratings. (See applicationtable, page 5).D

When the contactor is used withan inductionheater facility, the switchinglife of the vacuuminterrupter is approximately 250,000 operations. The vacuum interrupter should be replacedafter 250,000 operations.

2)

When the contactor is applied to a capacitor load, be sure to use a space heater to keepthe temperature above the dew point and prevent condensation. Be sure to use a heateradequately sized for the compartment in which the contactor is installed. The contactorShould always be applied with a protective power fuse.

3)

INSTALLATION

During installation, protect the contactor from dust and falling debris.

The following precautions should be taken;

1) The mounting surface should be horizontal (level : ±1 mm). If the mounting surface is notlevel, adjust with spacers or shims.

2) The contactor base has four (4) mounting holes. Use M8 or 5/16 bolts to securely mountthe contactor.

(

In wiring the main circuit, wires should be given sufficient length to be flexible for service.

The ground wires should be #10 AWG or larger.

Avoid touching the surface of the vacuum interrupter with soiled hands. You can damagethe silicon finish on the interrupter. If the interrupter becomes dirty, simply clean it with anon-tracking cleaner such as rubbing alcohol.

CONTROLS

The drive unit for the dosing coii assembly is installed in a cavity in the molded frame housing. Thedosing circuit can be operated by applying either AC or OC to this drive unit.The optional latch tripcircuit uses OC as standard. When a latched contactor is operated using AC power, it isrecommended that a capacitor trip device be used

The standard control voltage (factory preset) is 120V AC. To operate at other ratings see theselection chart below.

(TRIAL OPERATION

AWARNING MAKE SURE MAIN POWER IS OFF.After mounting and wiring of the vacuum contactor, make the following inspections.1) Check for any loose connections.2) Check for any wiring errors. Perform this test with only the control circuit energized.

Confirm that the operation Is correct. For the latched type contactor, check that the latchcorrectly engages and trips when the dose/trip signalsare applied.Also, manually trip thecontactor using the trip lever to verify proper operation. For latch kit adjustment andmaintenance please refer to manual no.6F9G0062 - Installation Instructions of Latch Kitsfor CV-6HA.
